How To Cook Bacon in the Oven – No Preheating Required

Why Cook Bacon Without Preheating?

  • Even Rendering: Starting with a cold oven allows the fat to render slowly, resulting in perfectly crispy bacon without burnt edges.
  • Flatter Bacon: Less curling and shrinkage as the temperature rises gradually.
  • Energy Efficient: No need to waste energy preheating your oven.


  • Baking sheet (rimmed is best)
  • Aluminum foil
  • Paper towels
  • Bacon (regular or thick-cut)
  • Optional: Cooling rack (for extra crispy bacon)


  • Prep: Line your baking sheet with aluminum foil for easy cleanup. If you’re using a cooling rack for extra crispiness, place it on top of the foil.
  • Arrange Bacon: Lay the bacon strips in a single layer on the baking sheet or cooling rack. They can touch slightly, but don’t overlap them.
  • Cold Start: Place the baking sheet with the bacon into a COLD oven. This is crucial!
  • Set Temperature: Turn the oven on to 400 degrees Fahrenheit (200 degrees Celsius).

Bake Time

  • Regular cut bacon: Start checking for doneness around the 15-minute mark. Total cooking time is typically in the 17-20 minute range.
  • Thick-cut bacon: Start checking for doneness at about 20 minutes. Could need up to 25 minutes total.

Desired Crispiness:

  • Look for the level of crispiness you prefer. Bacon will continue to firm up a bit as it cools.
  • You may want to rotate the pan halfway through the cooking time for even browning.

Drain and Enjoy:

  • When bacon is cooked, carefully remove the baking sheet from the oven.
  • Transfer bacon slices to a paper towel-lined plate to drain off excess grease. Serve immediately and enjoy!

Important Tips

  • Oven Variations: Every oven is slightly different. Use the suggested times as a guideline, and adjust based on your oven’s performance and your desired bacon crispness.
  • Don’t Crowd the Pan: If cooking a large amount of bacon, do it in batches to ensure proper cooking and airflow.
  • Store Leftovers: Bacon can be stored in an airtight container in the refrigerator for a few days and reheated if desired.
